HAIR WAVING PAD Filed May 27, 1955 11v VENTOR Jfi'd A ITTORNEY Patented May 11, 1937,

PATENT OFFICE HAIR WAVING PAD Joe 0. May, Kansas City, Mo., assignor to Mary C. Klapmeyer, Kansas City, Mo.

Application May 27, 1935, Serial No. 23,608 1 Claim. (Cl. 132-362) My invention relates to improvements in hair waving pads adapted for making permanent waves. It relates particularly to the type of such pads in which there is provided an envelope of 5 a pliable nature adapted to embrace a coil of hair wourd on a core of metal, and. having in it a material, as lime, which when wet will heat and produce steam, and thus heat and steam the hair, the envelope having a perforable side, normally 10 closed, which when the pad is to be used is perforated to permit the entrance of moisture from a wet cloth and the discharge of the steam produced.

My invention provides, as one object thereof,

15 novel means for applying oil to the hair while it is being treated, for protecting the hair from possible injury during such treatment.

A further object of my invention is novel means for supporting the oil in position for application 20 to the hair that is being waved.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which is illus- :rative of the preferred embodiment of my invenion:-

Fig. 1 is an inside elevation of my improved pad, prior to the perforation of the envelope and insertion of the moistening cloth.

Fig. 2 is a section on 22 of Fig. 1.

Fig. 3 is an inside elevation of the pad, with the inner side perforated, and the oiled sheet partly raised.

Fig. 4 is a section on the line 4--4 of Fig. 3.

Fig. 5 is an inside elevation, showing the oiled 35 sheet partly raised and the moistening cloth in its operative position.

Fig 6 is a section on the line 66 of Fig. 5.

Fig. 7 is an end view of the pad as applied to a coil of hair to be waved.

40 Similar characters of reference designate similar parts in the different views.

I designates a pliable envelope of rectangular form usually composed of tin foil and containing a substance, such as lime 2, which when moistened heats and produces steam from the water contacting with the lime. One side of the envelope is perforable, but to protect the lime, it is usually provided with the perforations 3, Figs. 3 50 and 4 just before being used.

To moisten the lime through the perforations 3, there is provided a wet cloth 4, Figs. 5 and 6, which is laid across the perforations 3.

My invention provides novel means for getting a protecting coating of oil on the hair while it is being treated, such novel means, in the form shown, comprising a flexible porous sheet 5, compri ing an absorbent material, such as flannel or most any porous cloth, the sheet being fastened adjacent to one of its edges to the envelope l adjacent to one of its edges, in any suitable manner, as by staples 6.

The sheet 5 is more or less impregnated with oil, such as olive oil, or castor oil, or the two oils combined. y

In use, a wet cloth 4 is inserted between the sheet 5 and the perforated side of the envelope l, following which the pad is formed into U shape, as shown in Fig. 7, with the oiled sheet 5 at the inner side and embracing a coil of hair I encircling a core 8 of metal or other good conductor of heat.

The pad may be clamped against the hair I by any suitable means, not shown, and so held until the waving operation is completed. The inner side of the pad is raised above the hair, as shown, and the ends of the pad are pinched to close them, thus forming above the hair I a chamber for receiving and holding the steam and oil vapor discharged therein.

As the lime 2 becomes moistened by water passing into the envelope I through the perforations 3 from the wet cloth 4, steam is produced from the water and passes through the perforations 3, through the wet cloth 4 and the oiled sheet into the chamber above the hair. The lime also becomes heated and heats the envelope and other parts, and also the hair which the pad embraces.

The steam passing through the oiled sheet 5 vaporizes the oil in the sheet and it is projected against the hair which is in the pad, thereby protecting the hair from any injurious effects due to its being heated. This oiling of the hair continues so long as the pad is effective-in its steaming and heating operation, thereby aflording protection to the hair during the whole operation of forming permanent waves therein.

As shown in the drawing, the oiled sheet 5 does not fully cover the perforated portions of the perforable side of the envelope I, thereby providing ample means for the discharge of steam from the envelope l around as well as through the sheet 5.

Many modifications of my invention, within the scope of the appended claim, may be made without departing from the spirit of my invention.

What I claim is:-

In a hair waving pad adapted to embrace the hair to be waved and comprising a pliable envelope having a perforable side and containing material which when wet willheat and produce steam, and a. moistened cloth next to said perforable side, the combination with said envelope, of a flexible porous sheet containing oil disposed against said cloth and adapted to be disposed next to the hair and to have steam pass therethrough from said cloth to said hair, whereby the oil is vaporized and contacts with and protects the hair from damage by the steam, and the steam moistens the hair and sets it in wave orm.
